Optimization of the main parameters of the root crop grinder

Abstract

Based on the results of experimental studies of the experimental root crop grinder, the dependence of the cutting force during grinding of root crop on the constructive and regime factors of the grinder was determined: αc - chevron angle, deg., αi - angle of installation of knives in the knife wall, deg., vk.w. – speed of the knife wall, m/s, hw – height of the knife wave, mm in the form of a regression equation. According to this equation, the dependencies of the influence of factors on the value of the cutting force are constructed. As a result of the processing of graphic material, the studied factors are determined at the optimal level: αc = 48...49 deg., αi = 26...27 deg., vk.w. = 0,92...0.94 m/s and hw = 1...2.
